A spin coater is widely used for thin film coating in nano/microtechnology. In this paper, a spin coater with inexpensive mechanical and electronic components was fabricated based on an open-source Arduino microcontroller. To measure and control the spin speed of the spin coater, two sensor types including two infrared (IR) light-emitting diodes…

An essential goal for physics and optical science instructors is to encourage students to find excitement and beauty in physical and optical phenomena while helping them learn the theoretical concepts and conducting experiments that can test the validity of the concepts. Such motivation largely relies on realistic hands-on lab opportunities where…

Information and Communication Technology specialists, working within universities play important roles in the deployment of educational technologies for teaching and learning. Given the centrality of these specialists and the woeful dearth of empirics on this subject-matter in Sub-Saharan Africa, this paper interrogates the perspectives of ICT…

Current distance education practices can be susceptible to the types of content-heavy, top-down instruction often seen in physical classrooms. These practices are similar to the activities of corporations, which use recommendation systems and game theory to mold the public sphere and fragment it. We propose that free knowledge creation through…

The Fourier transformation (FT) is a mathematical process frequently encountered by chemistry students. However, it remains an automated background process perceived by many students as difficult to understand. In this paper we present a simple open-source web application, which can help students to understand the basics of the FT applied to…

LiaScript is an attempt to enable everyone to create free and interactive online courses, without the need of being an experienced programmer. Instead, it aims to bring both parties, software- and course-developers, closer together by introducing Open-Source techniques into the Open-courSe development process. LiaScript was designed to be…

The use of large, open-source data sets is ubiquitous in scientific research. Scientists--ranging from meteorologists to chemists to epidemiologists--are researching and investigating critical questions using data that they have not themselves collected. To contribute to the growing effort to bring data science into classrooms, the authors have…

As an emergent technology augmented reality (AR) demonstrated a plethora of advantages in foreign language education, promoting motivation, memorization of contents, as well as contextualized learning. However, the majority of teachers are unfamiliar with AR, and their role as designers and facilitators requires further investigation. Moreover,…

The damped harmonic oscillator physics problem is a standard oscillation problem in calculus physics for pre-engineering students in a community college. The use of alternative linear algebra eigenvalue stability method is consistent with the upper engineering courses using control theory. The external force and friction damping would become the…

Teacher presence has been considered one of the cornerstones of students' motivation and engagement in traditional and online education. However, we argue that diminished teacher presence can actually be beneficial for building a democratic, student-led classroom. We hypothesize that this can be achieved through the use of an Open Source Educative…

The field of computer science has long been plagued by issues of diversity - in particular, attracting and retaining those historically marginalized in computing contexts. This is a great loss to the field, to the future of innovation, and to society. Perhaps most importantly, it is an incalculable loss to those populations excluded from pursuing…

Open source software has now become a significant alternative in meeting different needs in business, government and academic environments, such as needs related to economics, management, learning and innovation, among others. The purpose of this research was to examine the research trends and evolution of the field of open source software…

This work describes the construction of a small-scale radio telescope using open source hardware technologies which can be used as a tool in the training of engineers and physicists, as well as in the dissemination of important technologies for space weather monitoring studies, security of radio communication networks and maintenance of essential…

In this digital ITEMS module, Dr. Jeffrey Harring and Ms. Tessa Johnson introduce the linear mixed effects (LME) model as a flexible general framework for simultaneously modeling continuous repeated measures data with a scientifically defensible function that adequately summarizes both individual change as well as the average response. The module…

Learning cybersecurity awareness builds on basic information technology concepts and digital literacy skills. In an effort to raise cybersecurity awareness among information technology students, this paper describes a series of three different interactive sessions offered to students of all levels at a business university. The sessions introduced…
